The congregation of one of America's largest churches has lost 250,000 pounds.

California's Saddleback Church, led by Pastor Rick Warren, has been following "The Daniel Plan," based on the first chapter of the book of Daniel.

Warren himself has lost 50 pounds.

Members are replacing refined, processed foods in their diet with fresh fruits, vegetables and lean meats. They're also moving more.

"It's not about weight loss, it's about... We go through this life in a body and if our bodies are sick because we're not being careful, because we're not taking care of ourselves, we can't do the ministry God asks us to do," Warren's wife, Kay, said.

Warren said church members following the plan are getting off medications, have more energy, and are feeling better than ever.
